Johan is leading a team of technicians to replace his company's PCs. The function P(d) models
the number of PCs to be replaced, where d is the number of days since the project started.
[ The graph has days on the horizontal axis and Number of P Cs on the vertical axis. A line is
drawn from (0, 350) to (23, 0).]
Which statement is correct?
A) The point P(20) =/= 52 implies that there are still 52 more PCs to replace 20 days into the
project.
B) The point P(20) =/= 21 implies that there are 21 more PCs to replace 20 days into the project .
C) The point P(52) =/= 20 implies that there are 52 more PCs to replace 20 days into the project .
D) The point P(20) =/= 52 implies that there are 20 more PCs to replace 52 days into the
project . - CORRECT ANSWER-The point P(20) =/= 52 implies that there are still 52 more PCs to
replace 20 days into the project.
The equation for the best-fit line is y = 3.15x + 9.6. Consider the following graph.
[The graph has months on the horizontal axis and monthly sales in thousands of dollars on the
vertical axis. A line is drawn, which begins at (0, 10) and ends through (12.3, 47). A series of data
, points labeled from A to J, closely follow the line except E, which is is plotted at (5, 2).]© 2018

How would the line change if the outlier were removed?
A) The line would move up.
B) The line would tilt downward from left to right.
C) The line would move down.
D) The line would become horizontal. - CORRECT ANSWER-The line would move up.
The following graph shows the profit function for a company that sells blenders for $39.95 each.
[The graph has number of items sold on the horizontal axis and profit in dollars on the vertical
axis. A line is drawn which begins at the fourth quadrant, slopes up through (107, negative
2000) and (157, 0) and ends through (185, 1100).]
How many blenders must be sold for the company to make $1,000?
A) 180 blenders
B) 150 blenders
C) 133 blenders
D) 183 blenders - CORRECT ANSWER-183 blenders
